Wonder why someone is willing to spend $69.16 / click on school loan consolidation

My first post here is an interesting experiment ... since google generates its ads through relevant content, I wonder what would happen if there was a list of the most expensive adwords on a webpage. If (in theory) there were enough people reading this post, and curious enough to find out what each of these terms meant, there might be a lot of revenue through this simple exercise. Of course this is just an experiment, I will be donating the proceeds of this month (since it will get archived) to RedCross!
